Twinkies are back, but they may be a bit smaller than you remember.

The new boxes hitting shelves this week list the spongy yellow cakes as having 270 calories and a weight of 77 grams for two cakes, or 135 calories and 38.5 grams for one cake. A spokeswoman for Hostess, Hannah Arnold, said in an email Monday that the size change was made in “mid-2012” by the predecessor company. That would mean it happened in the months leading up to its bankruptcy. Arnold has also said that the longer shelf life of Twinkies reported earlier this month was made by the predecessor company right before it went bankrupt. The 45-day shelf life, up from 26 days, was a separate change and hit shelves Nov. 1, she said.
